Application filed September4, 1920. Serial No. 408,342.

' T all whom it may concern Be it known that I, HARRY S..UBER, a citizenof the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented cer-' tain new anduseful Improvements .in a .Pho- 1 tion is to provide a stop adapted toengagev the control-lever and prevent the latter from being shifted tostart the machine when the motor-spring is partially run down and thetension on the motor-spring is not suflicient to operate the machinefora per od of tlme long enough to play one full record, :thus

my invention will obviate the annoyance of themachine stopping duringthe .playingof a record. Thesetogether with various other novel featuresof construction and arrangement of the parts constitute my invention.

ildeferring .to the accompanying drawings Fig. 1, is an end elevation ofa portion of a phonograph embodying my invention; Fig. 2, is a plan viewof Fig. 1 ;'Fig. 3,1is a side elevation of Fig. 2; F 4, is a verticalsection on line 44 Fig. 3, showing the stoppin in'a positlon to hold thecontrol lever in the off position; and Fig; 5, ,a perspective of amodified form of my invention.

' "Referring to the drawings, in which like reference characters referto like parts, 1 represents the removable portion of the easing of aphonograph of any wen known type. d

A spring motor is secured to thecasingand consists of the housing 2, thewinding shaft 3, on which are mounted the motor-spring casings'4 and59nd to which shaft one end of the motor-spring 6 is attached. The disktable 7 is adapted to be rotated by the gear wheel 8 on the motor-springcasing 5'. The

winding shaft 3 has secured thereon a ratchet wheel 10, which is engagedby a pawl 12 for preventing the shaft 3 from turning by the action ofthe motorspring 6. The pawl 12, heretofore has been pivotally mountedupon a pin or shaft secured in the housing 2. In the present inventionthe pawl is mounted upon a movable member 14 adapted to be moved in onedirection by the tenslon 0f the motor-spring 6 and in the oppositedirection a counter spring 16 hav ing less tension than themotor-spring, when the latter-is partially wound, .so .that 'ithecounter spring 16 will actuate the movable member 14 ata predeterminedpoint in the unwinding of themotors'pring. The movable member 14 isassociated, throughlevers '26, 25, 30 and 32, with a stop pinl8;.adapted to be moved into the path ofthe control member or startingand stopping lever .20 and thus :prevent the latter from being shiftedto start the machine. The counterispring 16 1s made with sufli'cientpoWerto move'themovable member 14 against the action ofthe motor-spring"6 at .acertain'place in the un- I winding of the motor-spring.

If the motor will run the machine, as for example, a sufficient timeltoplay three full records and about half of a'fo'urth record,

the counterspring 1-6 is set so was to overcome the tension ofthemotorespring during the playlng oftheth'ird record. The movablemember isthusshi'fted Iby'the counter spring 1'6 and the stop pin 18 in turnisinoved into a .posrtionwhich will allow :the control mem- 1 her 20tobe moved to stop the machine at the end of the playingof'thethirdrecordr The pin 1 -8 will lock the control. member 20 in theF off position, .so that the-machine can not be again started 'forplaying the fourth recorduntil the motor is again wound" up and theincreased tension on the motorspring "6 shifts the movable. member I 14againstthe action of the counter springl6 and the movable member 14 inturn with draws the pin 18 out of the path of the con trol member 20.

The movable member 14, preferably consists of .a U-shape frame, moreclearly shown in Fig. 5,, which is loosely mounted upon the shaft 3 andis free to rotate thereon between stops 21 and '22 secured in thehousing 2.

12, which engages the ratchet wheel lO'and prevents the shaft 3 fromturning in a direction which would allow the motor-spring to unwind. Theshaft 23 extends beyond theframe 14 and formsa convenient place for Theframe 14 embraces the ratchet wheel 10, and has secured thereina shaft23, upon which latter is pivotally mounted the pawl attaching one end ofthe counter spring 16. The opposite end of said spring is attachedto-the housing 2 as clearly shown in'the drawings.

A link or connecting rod 25 is pivotally attached to the U-shaped frame14, in any suitable manner, preferably to the end of an arm 26 securedto, or forming part of, the frame 14. A rock-shaft 28 18 mounted inbearings 29 upon the housing 2, and is provided at one end with an arm30 to which the connecting rod 25 is attached. The opposite end of therock-shaft is provided with a spring-plate 32 adapted to lift the pin18,slidably mounted in a sleeve 19 secured in the casing 1.

The pin-l8 is adapted to engage the control member 20 and hold it in theoff position, as shown in dotted lines Fig. :2, in which position thecontrol member 20 engages the disk table '7 and holds the machine fromoperating.

The pin 18 is located upon'the casing l in alignment with the controlmember 20, when the latter is in the on position, as shown in full linesFig. 2. The pin 18, when lifted by the spring plate 32,will strikeagainst the underside of the control member 20, which latter preventsthe pin from being lifted to the full extent of its movement. The springplate 32 will yield and assume shown in dotted lines Fig. 1.

the position The control member 20 is therefore free to slide over thehead of the pin 18 and be moved either by hand or by the automaticstopping lever 34:, from the on to the off position. When the controlmember 20 is thus moved to the off position the pin 18 will be lifted toits full extent, by the spring-plate 32, as shown in Fig. i, and willoccupy a place in the path of the control member 20, thus pre ventingthe control member 20 from being shifted to the on position-until themotor is again wound sufiiciently to cause the tension of themotor-spring 6 to actuate the movable member 14 against the action ofthe counter spring 16, and thus move the parts into the position shownin full lines Fig. 1, in which the pin 18 has fallen out of the path ofthe control member 20 and the latter is free tobe moved by hand to againstart the machine.

.The movable member i l may be connected with a pointer 35, as shown inFig. 5, for indicating when the motor-spring should be wound. Themovable member 14 is connected by a link 36 to the arm 37 on arock-shaft 38 mounted in the casing 7 of the machine.

The hand or pointer 35 is secured to the rock-shaft 38 and is adapted tobe moved adjacent to a dial 39 having suitable indicatmoving the pinthrough the medium of the flexible member. a

2. A phonograph having in combination amotor-spring; a control memberforstarting and stopping the phonograph, a pin forming a stop to hold thecontrol member against starting movement, a sleeve in which the pin isslidably mounted, a yielding member for lifting the pin into the path ofthe control member, a rock-shaft in whichv the yielding member ismounted, and mechanismcontrolled by the relative tension of the motorspring for moving the rock-shaft.

3. A phonograph having in combination a motor-spring, .awinding-shaftfor said motor-spring, a pawl to hold the windingshaft against unwindingmovement, a mov-.

able member upon which the pawl is ful crumed, a spring to move themovable member against the action ofthemotor-spring when the latter ispartially rundown, a connecting rod pivotally attached at one end to themovable member, a rock-shaft actuated by the connecting rod, an arm uponsaid rock-shaft, a pin actuated by the said arm and a control lever forstarting and stopping the phonograph adapted to be engaged by said pinand held against startingmovement when the said movable member has beenshifted against the reduced tension of the motor-spring.
